DSC AND SCS DATA STREAM COMMANDS
SCS data stream structure
The SNA Character String (SCS) has a relatively simple structure
consisting of a 1-byte hexadecimal control code followed by the
data to be printed. Multiple control codes can be inserted into
SCS by printing applications in a specific order to achieve certain
types of output.
The SCS mode can also be referred to as SNA LU1 mode.
